A MAC Protocol supporting QoS in Wireless Sensor Networks
Hyun Joo Park, Seong‐Cheol Kim · 2009
Medium access control for wireless sensor networks has been a very active research area in the recent years. But the traditional wireless medium access control protocols are not suitable for the sensor networks because these are based on the battery power. In this paper, we proposed an efficient TDMA scheduling algorithm to support QoS (Quality of Service) for a clustered Wireless Sensor Network. It is known to be difficult to support QoS in WSNs. A dynamic scheduling algorithm according to the number of member nodes and node traffic load was suggested. Our proposed QS-MAC (QoS-Supporting MAC) could save energy, reduce transmission delay, and support QoS.
